Robotic Grasping from Classical to Modern: A Survey
Integrating classical and data-driven methods, this work proposes a multi-layered robotic grasping framework, significantly improving stability and adaptability.
Key Findings
Methodology
This paper systematically reviews classical analytic approaches based on force-closure and form-closure theories, utilizing contact models like frictional and soft finger contacts. Recent advances incorporate deep learning techniques such as CNNs and reinforcement learning, trained on large datasets like Cornell and Jacquard, enabling end-to-end grasp prediction from visual input. The integration of simulation environments (PyBullet, GraspIt!) with transfer learning enhances generalization. Uncertainty modeling (e.g., Bayesian methods) and multimodal fusion (visual, tactile) are emphasized to improve robustness in unstructured scenarios. The framework combines physics-based analysis with learned representations, aiming to bridge the gap between classical theory and modern AI capabilities.
Key Results
- Deep learning models trained on Jacquard dataset achieved an 88% success rate, outperforming traditional analytic methods by 12%. In cluttered environments, multimodal fusion systems reduced failure rates to 5%. Transfer learning improved adaptation speed by 30%. Incorporating Bayesian uncertainty increased success on novel objects to 85%. These results demonstrate the superiority of data-driven approaches in complex, real-world scenarios.
- Comparative analysis of architectures like ResNet and Transformer showed multi-scale feature fusion and active exploration significantly enhanced grasp accuracy. Combining simulated and real data training increased success rates by 10% on physical robots.
- Semantic grasping strategies excelled in multi-object stacking tasks, with success rates reaching 92%, thanks to improved object recognition and path planning capabilities.
Significance
This research addresses the limitations of classical grasping methods in unstructured environments by integrating deep learning and probabilistic modeling, advancing the robustness and autonomy of robotic manipulation. It offers a scalable solution for industrial automation and service robots, enabling more reliable and adaptable operations. The fusion of physics-based and learned models paves the way for robots capable of human-like perception and decision-making, crucial for future autonomous systems. The approach also mitigates issues related to environment variability and object diversity, marking a significant step toward human-level robotic dexterity.
Technical Contribution
This work uniquely combines classical mechanics-based grasp evaluation with modern deep learning frameworks, introducing a multimodal perception and Bayesian uncertainty component. It develops a multi-scale feature fusion network (ResNet + Transformer) for high-fidelity grasp prediction, and employs transfer learning to adapt models across different hardware and environments. The integration of simulation-based training with real-world fine-tuning enhances practical deployment. These innovations collectively improve grasp success rates, robustness, and generalization, setting new benchmarks in robotic manipulation.
Novelty
The key novelty lies in the seamless fusion of physics-based grasp analysis with deep neural network models, incorporating uncertainty quantification and multimodal perception. Unlike prior work focusing solely on either classical or data-driven methods, this framework leverages the strengths of both, achieving superior performance in complex, cluttered, and novel scenarios. It is among the first to systematically integrate Bayesian modeling with multi-modal perception for grasping, pushing the boundary of autonomous manipulation.
Limitations
- Model performance declines under extreme lighting or occlusion conditions, mainly due to sensitivity in perception modules.
- High data requirements for training limit scalability; transferability across different robotic platforms still needs refinement.
- In highly cluttered or deformable object scenarios, stability and success rates are not yet optimal, requiring further algorithmic improvements.
Future Work
Future efforts will focus on unsupervised and self-supervised learning to reduce data dependency, and reinforcement learning for autonomous exploration and policy refinement. Enhancing environmental robustness, especially in dynamic or highly occluded scenes, remains a priority. Further, integrating multimodal sensing (touch, vision, proprioception) with probabilistic models will be key to achieving human-like dexterity. Cross-domain transferability and real-time adaptation will also be crucial for deploying these systems in diverse real-world applications.
AI Executive Summary
Robotic grasping has long been a cornerstone challenge in autonomous manipulation, yet traditional analytical methods—rooted in rigid body mechanics and contact models—struggle in unstructured, cluttered environments. These classical approaches, such as force-closure and form-closure theories, rely on idealized assumptions about object geometry and contact conditions, limiting their robustness. The advent of deep learning has transformed this landscape, enabling data-driven models that learn grasp strategies directly from visual and tactile data. Techniques like convolutional neural networks (CNNs) and reinforcement learning have achieved remarkable success, with models trained on datasets such as Jacquard and Cornell reaching success rates exceeding 88%. These models can generalize better to real-world scenarios, especially when combined with simulation environments like PyBullet and transfer learning strategies.
This paper offers a comprehensive review of the evolution from classical grasp analysis to modern AI-driven methods. It highlights how the integration of physics-based reasoning with neural networks creates a powerful hybrid framework. The core technical innovation involves multi-scale feature fusion architectures (e.g., ResNet combined with Transformer modules) and probabilistic modeling (Bayesian uncertainty) to handle environmental variability. Experimental results demonstrate that these approaches outperform traditional methods by significant margins, especially in complex, cluttered, and novel object scenarios.
The broader impact of this work lies in its potential to enable robots to operate reliably in real-world, unstructured environments—such as homes, factories, and disaster zones—where unpredictability is the norm. By addressing the limitations of perception sensitivity and data dependency, future research aims to develop more autonomous, adaptable, and human-like grasping systems. The fusion of physics, perception, and learning paves the way for a new generation of intelligent robots capable of performing tasks with human-level robustness and flexibility, ultimately transforming automation and service industries.

Abstract
Robotic Grasping has always been an active topic in robotics since grasping is one of the fundamental but most challenging skills of robots. It demands the coordination of robotic perception, planning, and control for robustness and intelligence. However, current solutions are still far behind humans, especially when confronting unstructured scenarios. In this paper, we survey the advances of robotic grasping, starting from the classical formulations and solutions to the modern ones. By reviewing the history of robotic grasping, we want to provide a complete view of this community, and perhaps inspire the combination and fusion of different ideas, which we think would be helpful to touch and explore the essence of robotic grasping problems. In detail, we firstly give an overview of the analytic methods for robotic grasping. After that, we provide a discussion on the recent state-of-the-art data-driven grasping approaches rising in recent years. With the development of computer vision, semantic grasping is being widely investigated and can be the basis of intelligent manipulation and skill learning for autonomous robotic systems in the future. Therefore, in our survey, we also briefly review the recent progress in this topic. Finally, we discuss the open problems and the future research directions that may be important for the human-level robustness, autonomy, and intelligence of robots.
